Some rocks are more resistant to weathering than others. It depends on 1. the rock's chemical .... and 2. the rock's ..... Denser rock weathers more slowly than a rock with less density. Rocks that are already broken down into smaller pieces will weather faster because there is more....exposed to the agents of weathering that can occur.
